Hello!

To show our appreciation of Windows Phone customers, we are giving you an extra 20 GB of free SkyDrive storage for one year. This is in addition to the 7 GB of free SkyDrive storage that all customers currently have.

SkyDrive is built into your Windows Phone. It’s personal online storage that you can access – along with the photos and files you save there – at SkyDrive.com from any Internet-enabled device, and through the SkyDrive mobile app.

To apply this storage to your account, click here by January 31, 2014.*

If you are a Windows Phone user, you must check your inbox to see if you have received an email from “Windows Phone” with the subject “Windows Phone customers: 1-year SkyDrive storage increase (respond by January 31)‏” to avail the free storage on SkyDrive before deadline passes.

Earlier the Skype offered a year’s worth group video calling, a premium feature that normally costs €5,99/month or €71,88/annum with other features like Group Screen Sharing and Live Chat Customer Support.
